That's the first reason, the second is that we also want to report the unknown value if it's not recognized by the driver. For u8/enum parameters the value may possibly be set to a value older driver doesn't understand, but users should still be able to set them to one of the known ones. We'd also like to add that to 'fw_load_policy'. WDYT?
